[SOLVED] Matrox on Windows

I've been all day struggling to configure a Matrox tripleHead2Go Digital Edition (DVI connectors) with three projectors. I would appreciate any help.

- Computer is a laptop Acer i7 with Geforce 920, which is compatible with the hardware, according to https://www.matrox.com/graphic...- Software was download from the web and installed. It showed a message saying "the installation was completed with errors", but I couldn't figure out which errors (there wasn't a clear report).

- The Matrox GXM Quick Setup is using my onboard Graphics Card (see pucture bellow). Shouldn't it be using the offboard card?

- I use a DVI/HDMI adapter to hook Matrox to computer. Could it affect performance?

I am not in my studio but in the matrox software / Mode management you can choose what are the definitions you can find. You have a limited number of possibilities, so you have to deselect some as to select new ones. After that I connect the power of the matrox directly to a plain 5V USB.

The issue was that matrox had not give me any 3x(something) option at the beginning.

First I found out that my only HDMI port is connected to my motherboard, not my graphics card (it's a laptop). After that, I managed to create a new custom resolution, 2400x480, the only one that worked, which was a partial solution due to very low resolution. So I ended up with three projectors with 800x480 each.
